Everything here look# like conventional animation techniques with one exception.  To get the scrolling, I'd create a super wide comp, animate each element then nest that comp into a regular sized one and animate its position. 
Over time you'll pick up techniques to speed up your workflow, but they can be more confusing when you're getting started.
